MATLAB图片折腾3

把视频抽帧，转化成图片

我的代码如下，成功实现
clc;
clear;
videofilename=‘k:\GraduationWork\Resource\video.wmv‘; %where you put the video file
video=VideoReader(videofilename);
frame_number=floor(video.Duration*video.FrameRate);
while hasFrame(video)
    image_name=strcat(‘e:\graduationwork\frames\‘,num2str(i),‘.jpg‘);
    frame=readFrame(video);
    imwrite(frame,image_name,‘jpg‘);
    frame=[];
end
